Hexahydro-1,3,5-tris(hydroxyethyl)-s-triazine, MEA-Triazine 78% is a high-concentration, water-soluble chemical widely used as a hydrogen sulfide (H₂S) scavenger in the oil and gas industry.
Also known as Monoethanolamine Triazine, its chemical name is Hexahydro-1,3,5-tris(2-hydroxyethyl)-s-triazine. It is particularly valued for its ability to react with hydrogen sulfide and help reduce H₂S concentrations in crude oil, natural gas and other oilfield production streams.
With an active content of 78%, MEA-Triazine offers an effective chemical solution for oilfield operators seeking reliable H₂S control, improved operational safety and efficient production processes.
MEA-Triazine is a nitrogen-containing heterocyclic compound with three hydroxyethyl groups attached to its triazine ring. Its molecular structure contributes to its water solubility and H₂S scavenging properties.

Hydrogen sulfide is a toxic and corrosive gas frequently encountered in oil and gas production. Controlling H₂S is essential for protecting workers, pipelines, storage tanks and processing equipment.
MEA-Triazine works through a chemical reaction with hydrogen sulfide. During the scavenging process, H₂S reacts with the triazine ring to form sulfur-containing reaction products, with dithiazine being a major product.
The theoretical reaction capacity is approximately two moles of H₂S per mole of MEA-Triazine.
Unlike physical absorption, this process chemically converts H₂S into other compounds, helping reduce the concentration of free hydrogen sulfide in the treated stream.
Proper chemical dosage, mixing, contact time and operating conditions are important for achieving effective H₂S removal.
Crude oil produced from certain reservoirs may contain significant amounts of hydrogen sulfide.
High H₂S levels can create serious safety and corrosion challenges during production, transportation and storage.
MEA-Triazine 78% can be injected into suitable crude oil treatment systems to reduce H₂S concentrations.
Typical applications include:
Crude oil sweetening
Oil production and gathering systems
Oil storage tanks
Pipeline transportation
Oilfield separation facilities
Crude oil loading and handling operations
By controlling H₂S levels, MEA-Triazine helps improve crude oil handling safety and supports compliance with customer product specifications.
Natural gas containing hydrogen sulfide is commonly referred to as sour gas.
H₂S must be controlled before natural gas can be transported or used in many applications.
MEA-Triazine is widely used in gas treatment programs, including:
Natural gas sweetening
Sour gas treatment
Gas gathering systems
Pipeline H₂S control
Associated petroleum gas treatment
Biogas desulfurization applications
Depending on the gas composition and treatment requirements, MEA-Triazine can be applied through direct injection or dedicated gas-liquid contact equipment.
It helps reduce H₂S concentrations and improve the quality of treated gas.
Produced water is generated during oil and gas extraction and often contains dissolved sulfides, hydrocarbons, salts and other contaminants.
Dissolved hydrogen sulfide and sulfides can cause unpleasant odors, corrosion and operational difficulties in produced water systems.
MEA-Triazine 78% can be used as a sulfide scavenger in suitable produced water treatment programs.
Potential application areas include:
Oilfield produced water treatment
Water injection systems
Oilfield wastewater treatment
Produced water storage and handling
Water disposal facilities
Industrial wastewater systems containing dissolved sulfides
The required dosage depends on sulfide concentration, water chemistry, pH, temperature and contact time.
Microbial contamination is another challenge in industrial water systems and oilfield operations.
Sulfate-reducing bacteria (SRB), for example, can contribute to hydrogen sulfide generation and microbiologically influenced corrosion (MIC).
Industrial biocides are commonly used to control microbial growth in produced water and industrial water circulation systems.
Certain triazine-based compounds and formulations are also used in industrial preservation and microbial control applications.
However, it is important to distinguish between H₂S scavenging and biocidal performance. MEA-Triazine 78% is primarily an H₂S scavenger, and its suitability as a biocide must be verified through product-specific efficacy testing.
For oilfield chemical suppliers and industrial customers, selecting a reliable H₂S scavenger is important for maintaining operational efficiency and controlling treatment costs.
MEA-Triazine 78% offers several advantages:
High Concentration: 78% active content provides a concentrated solution for industrial chemical dosing.
Effective H₂S Scavenging: Reacts chemically with hydrogen sulfide to reduce its concentration.
Water Solubility: Suitable for many aqueous oilfield treatment applications.
Flexible Dosing: Can be incorporated into appropriate chemical injection and contact systems.
Wide Industrial Relevance: Suitable for different oil and gas production and treatment operations.
